inclinedFilmNusseltHeight

Description

The inclinedFilmNusseltHeight is boundary condition that provides a film height boundary condition for inclined films that imposes a sinusoidal perturbation on top of a mean flow rate, where the height is calculated using the Nusselt solution.

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            inclinedFilmNusseltHeight;
    GammaMean       <Function1<scalar>>;
    a               <Function1<scalar>>;
    omega           <Function1<scalar>>;

    // Optional entries
    filmRegion      <word>;

    // Inherited entries
    ...
}

where:
